Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

The very short version of the report’s background finding is that, for several years, analysts at the FBI blithely and illegally circumvented even the minimal checks on their power to demand telephone records under the PATRIOT Act. I’ll go into this further in a future post, but there are strong indicators that the agents involved knew they were doing something shady. Thousands of records were obtained using a basically made-up process called an “exigent letter” wherein they ask for records with what amounts to an IOU promising legitimate legal process any day now. (In many of those cases, the legitimate legal process would not actually have been available for the records obtained.) Still more disturbing, an unknown number of records were obtained without even this fictitious process: Agents simply made informal requests verbally, by e-mail, or via post-it note. And hey, why bother with subponeas or National Security Letters when you can just slap a sticky on someone’s monitor?

Treated to a preview of the OIG’s damning conclusions, the FBI was eager to find some way to cover its massive lawbreaking. So they apparently crafted a novel legal theory after the fact, in hopes of finding some way to shoehorn their actions into federal privacy statutes. On January 8—as in four weeks ago, years after the conduct occurred—the Office of Legal Counsel seems to have blessed the FBI’s theory, which unfortunately remains secret. Democratic Sens. Russ Feingold, Dick Durbin, and Ron Wyden have asked the Justice Department for details, but at present we just don’t know what kind of loopholes DOJ believes exist in the law meant to protect our sensitive calling records.

Communications records are generally protected by Chapter 121 of Title 18, known to its buddies as the Stored Communications Act. The few snippets of unredacted material in the OIG report suggest that the FBI’s argument is that the statute does not apply to certain classes of call records. Presumably, the place to look for the loophole is in §2702, which governs voluntary disclosures by telecom firms. There is, of course, an exemption for genuine emergencies—imminent threats to life and limb—but these, we know, are not at issue here because most of the records were not sought in emergency situations. But there are a number of other loopholes. The statute governs companies providing electronic communications services “to the public”—which encompasses your cell company and your ISP, but probably not the internal networks of your university or employer. The activity at issue here, however, involved the major telecom carriers, so that’s probably not it. There’s another carve-out for records obtained with the consent of the subscriber, which might cover certain government employees who’ve signed off on surveillance as a condition of employment. We do know that in some cases, the records obtained had to do with leak investigations, but that doesn’t seem especially likely either, since the FBI claims (though the OIG expresses its doubts about the veracity of the claim) that the justification would apply to the “majority” of records obtained.

My current best guess, based on what little we know, is this. The SCA refers to, and protects from disclosure to any “government entity,” the records of “customers” and “subscribers.” But telecommunications firms may often have records about the calling activity of people who are not the customers or subscribers of that company. For example, reciprocal agreements between carriers will often permit a phone that’s signed up with one cell provider to make use of another company’s network while roaming. When these outside phones register on a network, that information goes to a database called the Visitor Location Register. You could imagine a clever John Yoo type arguing that the SCA does not cover information in the VLR, since it does not constitute a “subscriber” or “customer” record. Of course, it beggars belief to think that Congress intended to allow such a loophole—or, indeed, had even considered such technical details of cell network architecture.

My guess, to be sure, could be wrong. But that just points to the larger problem: The Justice Department believes that some very clever lawyerly reading of the privacy statutes—so very clever that despite the rampant “creativity” of the Bush years, they only just came up with it a few weeks ago—permits the FBI to entirely circumvent all the elaborate systems of checks and balances in place (or so we thought) to protect our calling records. If investigators can write themselves secret exemptions from the clear intent of the law, then all the ongoing discussion about reform and reauthorization of the PATRIOT Act amounts to a farcical debate about where to place the fortifications along the Maginot Line.
